IMPROVEMENT IN SNOW-SCRAPERS.

Specification forming part of Letters Patent No. 149,619, dated April 14, 1874; application filed March 11, 1874.

To all whom it may concern.'

Be it known that I, WOODARD THOMP- SON, of Gardiner, in the county of Kennebec, State of Maine, have invented a certain new and useful Improvement in Snow-Scrapers, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same,

reference being had to the accompanying drawing, forming a part of this specification, in which` Figure l is a plan of the bottom of my improved scraper. Fig. 2 is a vertical transverse section of the same. i

Like letters refer to like parts in the different gures of the drawing.

My invention relates to that class of scrapers which are designed for removing and leveling the snow; and consists in a novel construction and arrangement of the parts, as hereinafter fully set forth and claimed, by which a simpler and more effective implement of this character is produced than is now in common use. The extreme simplicity of my invention renders an elaborate description unnecessary.

In Fig. l, A Z are the body or mold-boards; B, the rudder; E, the tongue; and G, a crossbar carrying the spring J, 011 which the drivers seat D is disposed. The boards A Z are provided with the auxiliary boards C F, interiorly arranged, as shown in Fig. 2, but not intersecting, there being a space, a, between the rear ends, through which the snow passes. In ordinary V-shaped snow breakers or scrapers, the tongue is attached to the opposite end from that in which the rudder in my scraper is placed; but the distinctive feature of my invention consists in a scraper with the tongue attached at the base or wide end, and provided with the auxiliary boards C F and rudder B.

It is well known that the snow in roads which are much traveled soon becomes rutted, and worn down to the ground, or so uneven as to render passing both difficult and dangerous. Myinvention is intended to obviate this dificulty by transferring snow from the vsides of the road, and depositing, it in the center, and also leveling it to make a good road-bed.

It will be seen that as the scraper is drawn along by the tongue E, the snowwill be gathered by the long arms or boards A Z, and taken up by the auxiliary boards O F, and, as the scraper proceeds, will be carried to the apex or rear, passed through the aperture a, and deposited in the center of the road, which will thus be turnpiked, and made to last much longer than would otherwise be the case. The rudder B may be rendered vertically adjustable by any suitable means, and serves to keep the scraper in place, much the same as the rudder of a ship serves to keep it on its course.

Having thus described my invention, what
